Aeroponics help needed please.....

Ideally try to keep your ph between 5.6-6 but slight slow swings wont hurt too much.

The PPM's are an agreement you'll have to make with your plants, you can get away
with not giving too much, but you *could* be sacrificing benefits of hitting the sweet
spot. Finding the sweet spot is a matter of watching your PPMs in your reservoir, if
your PPM goes up that means your plants are drinking more water and less nutes and
you need to back your ppm off. If your PPMs are lowering at a very quick rate, and
you didn't just tap off your reservoir, this signifies your plant is eating more nutes than
water and you need to up the nute level to find that perfect balance. Once you notice
your PPMs leveling out, with things looking healthy int he canopy, then this is the ideal
"sweet spot" where you want to feed. Takes some work finding and staying with it as
all strains are different, but definitely will benefit you and the plants.

This dude I think runs a few 36 sites https://www.rollitup.org/hydroponics-aeroponics/414460-gdp-36-site-aeroflo-led.html

I've run a couple of 60 sites for years and loved them, really great units just don't plan
on making your plants too huge with that density, and make sure your water temps are
in check as well or you have a method of controlling root rot. Aero seems to give me
more problems with root rot for some strange reason than other methods. I really like
the root growth I get with a timer running the much hyped 1 min on 4 min off timing for
my pumps as well. Other than that keep your conditions in check and don't get lazy and
you should be golden with that setup.

thx for the quick reply disposition, how often do you change your res , and how does your feeding schedual work.

thx again

I've always done weekly change outs with the exception of veg units, just to keep it simple
and make sure no kind of weird buildups could happen. I've gone up to 3 weeks before
without any major issues, and have a friend who's basically never changed his res in his flood
table his entire flower cycle with plants that still look/smell delicious. I think it's really up to
how comfortable you feel with trying it out, but weekly flushes will help give you the best idea
of your NPK ratios.

My feeding schedule is pretty fucked at the moment as I'm a sucker for additives and recently
just added big bud, sweet, snow storm ultra, gravity, MOAB, hammerhead. Some additives
suggest I run my nutes at half strength, and combining some of them also adjusts how much
I mix in my feed too. Things seem to be going ok for the time, but I've been known to mess
up some crops trying stupid things with my nutes and additives, always trying to find that
killer combo that just produces ridiculous buds.
